Web9 Jan 2024 · Gas exchange occurs at the surface of the mesophyll cells in dicotyledonous plants. Plants both use and produce oxygen and carbon dioxide. Gases move in and out of leaves through stomata, which are open and closed by guard cells. Water is also lost through the stomata, so xerophytic plants are adapted to prevent water loss. WebStomata, the pores on the leaf epidermis, facilitate gas exchange in plants. Plants balance their CO 2 demands and water losses through the adjustment of stomatal size, density, and modulation (opening and closing of stomata); however, adjustments to stomatal size and density are only possible during stomatal ontogeny. Consequently, stomatal size and …
